I'm going to purchase a 9mm carbine (my first AR platform) and have narrowed it down to the CMMG MK9, Colt 6951, and full JP GMR13. The CMMG is attractive due to a good reputation and price (I can purchase one for less than $900), the Colt has a good reputation (about $1,250), the JP a great reputation but expensive (close to $2,000 if I'm not mistaken). I understand the advantages of going with a .223, but I'll be able to shoot the 9mm more due to range restrictions. I'd appreciate your comments regarding the advantages and disadvantages of these carbines. I don't want to buy at the low end and regret it. Thanks in advance, Dr.J
